WALL.

Specification of Letters Patent.

Application filed September 5, 1916. Serial no. 118,598

To all whom it may concern:

Be it known that I, l lnrzns'r VVEISSBRODT, architect, a citizen of Switzerland, residing at Lausanne, Canton of Vaud, in the Confederation of Switzerland, have invented certain new and useful Improvements in WValls, of which the following is a speci iication.

The present invention relates to a wall and in carrying out the same I employ tiers of blocks so constructed and arranged as to provide communicating air Spaces in the wall. Alternate tiers of blocks are arranged parallel to the faces of the wall so that between them a free space is provided, and the blocks in intermediate tiers are placed transversely in the wall and are provided with channels or passages so disposed as to connect the free spaces between the blocks of the alternate tiers, for the purpose of obtaining within the wall at least one air layer all the parts of which communicate with each other. a

The blocks of the intermediate tiers may be provided with projections which extend into the spaces between the blocks of the alternate tiers, and these projections prevent the binding material which is placed be tween the different tiers from working into the channels and thus obstructing the same.

My invention is illustrated in the accompanying drawing in which- Figure l is a perspective view of my improved wall, and Figs. 2 and 3 are respec:

tively a side view and a plan view of one of the blocks of which the wall is made.

Thewall as illustrated is made of two groups of tiers of blocks which are alternately superposed in a regular manner. The blocks 6 in each alternate tier are placed in All the faces of these blocks are 1 plain, and the blocks are placed parallel to i the faces of the wall; the two rows being disposed at a certain distance from one another, in order to provide an air space 6 between their adjacent faces. The intermediate tiers consist of rows of header blocks 5 and 7 transversely arranged with the blocks in each row placed side by side within the wall with their end faces preferably parallel to the outer faces of the blocks 6. The upper and under faces of the blocks 5 and 7 are provided with projections 3 which extend into each of the spaces 6 between the tiers of blocks immediately above and below the same. In the blocks 5, 7 vertical channels or passages l of square or other cross-section, are provided, and extend transversely through the block so as to open into the adjacent air spaces (5 and thus connect the same. Within the wall, there is therefore an air space of which all parts communicate with each other. The projections 3 are of sufficient height to prevent the mortar or cement which is laid between the adjacent blocks from working into the channels 4L and thus obstructing'the same, Whereby the communication between the different parts of the air space is assured.

The blocks 5, 7 may further be provided with channels 2 of circular or other crosssection as is shown by the dash-dotted lines in Fig. 3.

It will be understood that I do not limit my invention to the precise construction herein shown and described, as variations may be made in the form of the blocks and Patented Oct. 2, 1 91 in the manner of making communication beheaders which span the space between the rows of blocks in alternate tiers, and are provided with transverse passages whereby there is in the wall a plurality of air spaces each in communication with all the others.
